<p>A part connection device is provided in a refrigerant circulation cycle for circulating a refrigerant, and connects members to be coupled so as to be in communication with each other, said members to be coupled being three constituent parts constituting the refrigerant circulation cycle. The part connection device comprises: a block-shaped joint member which has connecting openings formed so as to be opened on each end face that contacts a member to be coupled, and an internal channel which is in communication with all connecting openings, said block-shaped joint member allowing communication between the members to be coupled via the internal channel; a male joint member that is a cylindrical body supported in a situation of being inserted in the connecting opening, has a seal which is in contact with the inner wall of the connecting opening and prevents refrigerant from leaking from the inner channel to the exterior, said male joint member coupling the block-shaped joint member to each of the members to be coupled; and a fixture for fixing each of the members to be coupled to the block-shaped joint member.</p> |
